Reduction of Color and COD of Anaerobically Treated Distillary Wastewater by Electrochemical Method

Water pollution control is presently one of the major thrust areas of scientific research. While colored organic compounds generally impart only a minor fraction of the organic load to wastewaters, their color renders them aesthetically unacceptable. Stringent regulating measures are coaxing industries to treat their waste effluents to increasingly high standards. Various studies have been carried out here in reduction of color and COD from anaerobically treated distillery wastewater by electrochemical method which showed a good reduction in color (97-98%) and COD (70-72%). The optimized parameters for the process are Electrode distance 1cm, initial pH 4, current density 2 Amp/dm2 for 3 hours and color and COD reduction observed are 97.8% and 68% respectively.
